The X-56A Multi-Use Technology Testbed (MUTT) is a prototype unmanned aircraft made of lightweight, flexible materials that's being developed by the Air Force Research Laboratory in collaboration with Lockheed Martin. Its long, thin wings (28 feet across) are susceptible to vibrations, or flutter, that results from air flow and turbulence. Engineers plan to use MUTT's flight-control software to find ways to minimize flutter. That knowledge will inform the design of the proposed X-54 aircraft, which is intended to demonstrate technologies that muffle sonic booms, potentially opening the door to supersonic commercial flights over the United States.
